构建项目时出现以下错误:
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Lorg/slf4j/impl/StaticLoggerBinder;
at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594)

at com.android.dx.command.dexer.Main.main(Main.java:199)
at com.android.dx.command.Main.main(Main.java:103)
据我所知,这是因为我有多个依赖于slf4j的库。 build.gradle文件中的依赖项是:
dependencies {
compile project(':libraries:some-sdk')
compile files('libs/some-library.jar')
compile 'com.some-module:some-artifact:X.X.X'
compile 'com.github.tony19:logback-android-classic:1.1.1-3'
}
我知道logback-android-classic依赖是问题,因为它确实依赖于slf4j,如果我评论说我的项目构建正常。根据其他消息来源,我发现这通常是通过排除传递依赖性来解决的:
compile('com.github.tony19:logback-android-classic:1.1.1-3') {
exclude group: 'org.slf4j'
然而,即使在我清理和重建之后,我仍然会收到错误。
更新: 运行dependencyInsight寻找slf4j作为dmahapatro建议没有返回结果:
$ gradle -q dependencyInsight --dependency slf4j --configuration compile
No dependencies matching given input were found in configuration ':main:compile'
我的完整依赖树是:

更新2:
我已将冲突缩小到logback-android-classic库和本地jar(遗憾的是,由于许可问题,我无法直接编辑此jar)。排除其中任何一个解决冲突,以及只有这两个依赖项的空通用测试应用程序将产生冲突。我已经验证本地jar包含org.slf4j,但由于上述许可问题,我无法做到这一点。所以我唯一的选择就是从logback-android-classic中排除slf4j。鉴于依赖树实际上并没有将slf4j显示为logback-android-classic的依赖关系,并且考虑到添加
compile('com.github.tony19:logback-android-classic:1.1.1-3') {
exclude group: 'org.slf4j'
}
还没有解决问题,如何从logback-android-classic中排除slf4j依赖?
最后更新: 最终通过与我正在使用的本地jar的所有者合作来解决这个问题。我怀疑这对未来的访问者来说是一个特别有用的答案,但是为了完成它想要包含它。
答案 0 :(得分:0)
我在我的" build.gradle"中添加了以下内容:删除" slf4j"的传递依赖问题。这是排除依赖关系的方法,因此不会传递加载。并通过在"编译组"中提及它来明确加载冲突库。声明。认为它可以帮助你。
